IMPROVEMENT IN SAFETY-CLEVISES.

Specification forming part of Lettels Patent No. 165,253, dattd Julyu, 1875; application filed May 8, 1875.

Be it known that I, CHARLES N. POUND- STONE, of Grand Ridge, La Salle county, Illinois, have invented a new and useful Improvement in Safety-Glevis, of which the following is a specification Figure 1 is a side view of my improved clevis, part being broken away to show the construction; and Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved clevis for connecting the double-'tree and whifletrees with each other, which'shall be so constructed that it cannot become accidentally detached, and which shall have no loose parts to get lost, and thus cause delay and annoyance.

The invention consists in the clevis forme of the two hooked-shaped parts pivoted to each other at their bends, and Vthe pin swiveled to the long arm of one of the said parts, and working loosely in the long arm of the other part, ashereinafter fully described The body or bow of the clevis is made in two similar hook-shaped parts, A B, which are pivoted to each otherfat the bow or bend, in such a way that the short arm of each part may overlap the long arm of the other part, as shown in Figs. l and 2. The adjacent sides of the parts A B are attened, so that they may fit snugly upon each other. G is the clevis-pin, which is swiveled to the long arm of one of the parts A B.

In using the clevis the long arm of one of the parts A B is turned back, the clevis is Vthe pin G is passed down through the hole in the said doublegtree D, which hole is made nearer the back of the double-tree than its front, in the usual way.

The short arms of the parts A B are made of such a length as to overlap the upper and lower sides of the double-tree D when the lower part B of the clevis has been raised upon the pin G, and the clevis swung around to the forward side of the `double-tree D.

4By this construction the lower part of the cleviscannot drop off' the lower end of the pin C, and the clevis cannot become detached when upon the forward side of the double-tree in working position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The elevis formed of the two hookshaped parts A B, pivoted to each other at their bends, and the pin C, swiveled to the long arm of one of the parts A B, and working rloosely in the longarm of the other part,s1fbstantia1ly as herein shown and described.
